MyPC picked up something called Antivirus System Pro which I have found out is a rogue software. It keeps popping up messages saying this or that is missing or won't work and wanting me to update my antivirus software. How do I remove it without harm to other programs/files? Thanks

The problem with some of these bogus "antivirus" malware programs is that as long as they're running in the computer's memory, they may try to recreate their own files on disk if you try to delete them and may have various other tricks built in to make them very difficult to eradicate, such as using random file names to allow them to elude real anti-virus and anti-malware programs. The criminals who perpetrate them often demand money to remove the software from your computer, hence such programs are sometimes called "ransomware".

Antivirus System Pro cripples Microsoft Internet Explorer's ability to connect to the Internet. If you have another browser already installed, such as Opera or Firefox, you may be able to connect with them to get the malware removal tools; if not, you'll need to use another, uninfected machine and bring the tools over on a USB flash drive.

If your machine is still running otherwise, but the malware windows are popping up over all other program windows and can't be minimized, making it impossible to use the computer, you may still be able to push them aside. Make sure the malware window isn't maximized, then grab the title bar and drag it to the edge of the screen, pushing as much of the window as you can off-screen. This will allow you to start up your alternate browser so you can get on-line and look for ways to remove the malware.

Using Google or your favorite search engine, plus the program name you noted earlier, look for sites that may discuss removal. I tried entering "antivirus system pro removal tool" in Google and immediately came up with several promising hits at the top of the results. The one I'd suggest first is "Remove Antivirus System Pro (Uninstall Guide)" at

The procedure calls for use of a couple of free, automated malware removal programs, linked from that page, plus a few simple manual steps. Follow the instructions step-by-step and you should have your machine back to its old self in short order.

What kind of antivirus do you have installed? A good free one for personal use is Avast! antivirus. You may want to check out this program. Free and very effective.
Thank you,

Go to windows update page and download or search in the search box windows defender download it and then after downloading it reboot and run it in safe mode so it will kill any bugs it finds, if that does not help go to malwarebytes and download their 30 day free trial to remove it. otherwise YOU WILL HAVE TO FIND THE NAME OF THE PROGRAM IN REG-EDIT AND DELETE THE FILE NAME OUT OF ALL YOUR REGESRTY areas, don't do this if you don't know how, and sorry about the caps.

I think you have been attacked by a rogue antivirus. It claims to be an antivirus or some sort of security software, but it actually isn't. You can get rid of it by creating a new user account by going in to the control panel. Afterwards, restart the PC and get in to that user account. From that account you will be able to go to the internet. Open up the browser and go to this website and download that Anti-malware security suit, install it and run it. Do a quick scan and delete all the threats that are detected. Make sure you delete it from the quarantine folder as well. After that, restart the PC and log in to your regular account. Do that same from that account. If all the things are done, you won't see that rogue software in the computer. You can delete the other user account you've just created after that.

Rogue Virus Alert

There is a string of "viruses" out right now that will completely take over your computer. These make it hard to even restore your computer, as they block just about everything that they can. There are ways to avoid these and most people don't know that they aren't safe which is the main reason for the wide spread rogue. They look just like a legitimate antivirus or scan tool, however they are a virus of sorts in themselves. They will pop up on your screen and tell you that your computer has viruses on it and you need to download and run their scan, and although it is not something you need to download to have your computer infected, DO NOT do this.. it will ask for your cc # and the hackers behind the rogue will now have access to your cc info. There are many different types but they are all basically the same, or similar looking. Even though you have an antivirus program already installed, such as Norton or Mcafee, this does mean that you are exempt from this hoax. Tips for keeping your computer in good health and your personal info safe... keep your antivirus definitions up to date, run a complete scan on a regular basis, do not open any suspisious emails, do not enter any financial info into any pop up window. In addition to the above, depending on what antivirus you are using, don't trust any other "removal tool" Norton and Mcafee will always have their logo on their popups and in rare instances that they do pop up, it will not be in an overwhelming manner. Go to and search for antimalware malwarebytes. Download and install this, run the full system scan, do this on a regular basis and you should be ok. Just avoid anything that is suspicious. If by chance you run into this pop up removal tool, disconnect your internet connection leave the window up and run a system scan with both Norton and the antimalware that you downloaded. Between the 2 of these it should be caught before it is too deeply integrated into your system. Also, always make sure that you have your most important files backed up, just in case a restore is necessary. I hope this helped out and raised some awareness about these rogue viruses that are running rampant lately! Be careful!

while I am not familiar with the "eset" A/V program (actually never heard of it before) I would STRONGLY suggest that you go to their website and try whatever forums may be there first as that anything that we would have to say might very well "kill" your system because there are SO many versions of WIN XP (OEM, Home Pro, etc) and they would have VERY intimate knowledge of the software that you are using.

HOW TO REMOVE antivirus pro 2010

Hello, try to install Malwarebytes antimalware or Superantispyware. It can automatically disinfect this virus. Try if it is not blocked by this rogue software.

Or check out Avast or Avira. Also check out its bootable cd antivirus that runs best on safe mode or DOS mode.

Install, update then scan.
